Abstract
Dispositif de sécurité contre une surpression se produisant dans la partie huile (3) d'une pompe transfert fournissant un carburant tel que de l'essence à haute pression pour un moteur en ce qu'il est constitué par le joint tournant d'étanchéité (10) séparant la partie huile (3) de la pompe et la partie huile (7) dudit moteur.Safety device against overpressure occurring in the oil part (3) of a transfer pump supplying a fuel such as high-pressure gasoline for an engine in that it consists of the rotary seal ( 10) separating the oil portion (3) from the pump and the oil portion (7) of said engine.
Description
La présente invention concerne un joint tournant d'étanchéité qui, tout enThe present invention relates to a rotating seal which, while
assurant une bonne étanchéité statique et dynamique doit pouvoir être expulsé de son logement lorsqu'il est soumis à une surpression. ensuring a good static and dynamic tightness must be able to be expelled from its housing when it is subjected to an overpressure.
Cette invention et le problème auquel elle apporte une solution seront décrits ci- après en relation avec la figure unique qui est une représentation schématique. This invention and the problem to which it provides a solution will be described hereinafter in connection with the single figure which is a schematic representation.
Sur cette figure la référence 1 désigne une partie d'un bloc moteur et la référence 2 désigne une partie d'un carter de pompe. In this figure the reference 1 designates a portion of a motor unit and the reference 2 designates a portion of a pump housing.
De préférence la pompe est une pompe du type pompe transfert comportant une partie huile et une partie essence de façon à pouvoir fournir de l'essence à haute pression. Preferably, the pump is a pump of the transfer pump type comprising an oil part and a gasoline part so as to be able to supply gasoline at high pressure.
La figure étant schématique seule est représentée avec la référence 3 une portion de la partie huile de la pompe. The figure being schematic only is represented with the reference 3 a portion of the oil portion of the pump.
Cette partie huile 3 est traversée par un arbre 4 qui est l'arbre de la pompe. Cet arbre 4 est relié à l'arbre moteur 5 par un mécanisme d'accouplement 6. This oil portion 3 is traversed by a shaft 4 which is the shaft of the pump. This shaft 4 is connected to the drive shaft 5 by a coupling mechanism 6.
L'enceinte 7 qui se trouve dans la partie 1 du bloc moteur contient un brouillard d'huile du moteur. The enclosure 7 located in the part 1 of the engine block contains a motor oil mist.
Le problème à résoudre est le suivant. The problem to solve is the following.
Une défaillance d'un composant de la pompe transfert peut entraîner une montée brutale de la pression de l'huile se trouvant en 3. A failure of a transfer pump component can cause a sudden rise in oil pressure at 3.
Il s'avère que si aucun moyen de sécurité n'est prévu cela peut entraîner la rupture d'un composant de la partie huile et une fuite externe. Cette fuite externe n'est pas admise: par contre une fuite de la partie huile 3 vers l'enceinte 7 est acceptable. It turns out that if no means of safety is provided it can cause the rupture of a component of the oil part and an external leak. This external leakage is not allowed: on the other hand a leak of the oil part 3 to the enclosure 7 is acceptable.
Il serait possible de disposer un clapet de surpression dans l'enceinte 3, mais cela entraînerait une augmentation non négligeable du prix de fabrication de la pompe transfert, laquelle doit équiper des moteurs d'automobiles et doit donc être d'un prix de revient aussi bas que possible. It would be possible to have a pressure relief valve in the chamber 3, but this would cause a significant increase in the manufacturing price of the transfer pump, which must equip automotive engines and must therefore be a cost too. as low as possible.
La solution, selon l'invention, consiste à employer le joint tournant 10, qui sépare les enceintes 3 (partie huile de la pompe) et 7 (partie huile du moteur) comme un clapet de sécurité à rupture. The solution according to the invention consists in using the rotary joint 10, which separates the enclosures 3 (oil portion of the pump) and 7 (oil portion of the engine) as a rupture safety valve.
Dans ce but ledit joint tournant 20 est constitué de deux parties concentriques 10a et 10b de matières ayant des duretés différentes. For this purpose said rotary joint 20 consists of two concentric portions 10a and 10b of materials having different hardnesses.
La partie interne l0a est constituée en une matière dure, par exemple un caoutchouc d'une dureté shore de 80; tandis que la partie externe ou couronne 10b a une dureté inférieure. L'épaisseur de cette couronne externe 10b est faible par rapport à celle de la partie interne 10a. The inner part 10a is made of a hard material, for example a rubber with a shore hardness of 80; while the outer portion or ring 10b has a lower hardness. The thickness of this outer ring 10b is small compared to that of the inner portion 10a.
Le joint bi matière 10 est, de façon usuelle emmanché à force dans l'orifice 11 qui sépare les enceintes 3 et 7. L'arbre 4 tourne à l'intérieur de la partie 10a du joint tournant 10, qui demeure fixe dans son logement. The bi-material seal 10 is, in the usual way forced into the orifice 11 which separates the enclosures 3 and 7. The shaft 4 rotates inside the portion 10a of the rotary joint 10, which remains fixed in its housing .
En cas de surpression brutale dans l'enceinte 3, le joint bi matière 10 sera expulsé de son logement 11 selon la flèche F ce qui aura le double effet d'une part de faire tomber la surpression et d'autre part de récupérer la fuite d'huile ainsi provoquée dans le circuit d'huile du moteur: il n'y aura donc pas de fuites externes d'huile, ou de carburant ou encore d'un mélange huile carburant. In the event of a sudden overpressure in the enclosure 3, the bi-material seal 10 will be expelled from its housing 11 along the arrow F, which will have the dual effect of on the one hand relieving the overpressure and on the other hand of recovering the leak. of oil thus caused in the engine oil circuit: there will be no external leakage of oil, or fuel or a fuel oil mixture.
